Anecdotal evidence and recent theoretical models argue that past stock returns affect subsequent stock trading volume. We study 3,000 individual investors over a 51 month period to test this prediction using linear panel regressions as well as negative binomial panel regressions and Logit panel...

This paper reports the results of experiments on portfolio choice in the presence of nontradeable income. The nontradeable income part could either be riskless or risky (background risk). In many cases, we observe behavior which is qualitatively consistent with the predictions of normative...

For a longer investment period investment consultants use to recommend a larger proportion of risky assets in investors' portfolios. In an experiment we examine the effect of different investment horizons on investors' risk behavior. We are interested both in the participants' risk perception...

The cost of information is an often ignored factor in economic situations although the information acquisition behavior of the decision makers has a crucial influence on the outcome. In this experiment, we study an information aggregation process in which participants decide in a random...

In this study, we analyze whether volatility forecasts (judgmental confidence intervals) are influenced by the specific elicitation mode (i.e. whether forecasters have to state future price levels or directly future returns as upper and lower bounds). We present questionnaire responses of about...

Investors and academics increasingly criticize that features of employee stock option (ESO) programs reflect rent-extraction by managers (managerial power view). We use a unique European data set to investigate the relationship between the design of ESO programs and corporate governance...

If individuals have to evaluate a portfolio (or sequence) of lotteries their judgment is influenced by the portfolio presentation mode. Experimental studies (Redelmeier and Tversky, 1992, Benartzi and Thaler, 1998) found significantly higher acceptance rates for a sequence of lotteries, if the...

Portfolio choice is usually modelled by von Neumann-Morgenstern utility. Risk-value models are more general and permit the derivation of risk-value efficient frontiers. A behaviourally based risk measure with an endogenous or exogenous benchmark is used to derive effcient portfolios and to...
